This invention relates to paper making essary to stop the operation ofthe machine in order to prevent the continued feed of the web in rear ofthe break, from accumulating ive the workman opportunity .to reestab 1shthe proper feed. Such cessation of operation of the machine is of courseobjectionable in that it causes delay in operation, reduced output, andother objections. On the other hand it the machine is not shut down, thecontinued feed of the webwill cause the paper to accumulate and pile upin the presses or dry ers or other parts of the machine, according tothe point at which the parting of the" web occurs, and this results inserious obj ections and; injury to the parts, and danger and discomfortto the workman. For m stance, the undue accumulation of broke or wastepaper ontothe broke troughs of the presses, will cause the-material tofall down on the felts and breakor strain them when the broke is passedby the felt to the next press. And the accumulation of the broke in thedryers necessitates much time in the removal of the waste material,usually accomplished by long spears manipulated by the workmen, frequentinjury to the workman standing by, or injury to the dryer canvas orother parts. j

In accordance with the present invention these objections and othersincidental to the accidental parting of the web, are avoided by theprovision of controllable means for causing the break of the webautomatically by the accidental parting of the web, at a point in rearof that where the parting takes place, so although the machine willcontinue in motion, it will cease to feed the web m a way which willcause the accumulation of the broke in the machine and the objectionsincident to such accumulation.

The invention also contemplates signaling means brought automaticfllgmtoopparts.

eration by the accidental parting of the web,

whereby an indication will be given the workman at once of such parting.

Means andmechanism of diiferent forms and construction may be employedin accordance with my invention in efiecting these objects, and in theaccompanying drawings '1 have illustrated one exemplification of suchmeans and mechanism, in which a fluid blast or jet is em loyed, adaptedto impinge against the trave ing pa er web at the point in the machinewhere t e web asses from the couch roll to the first press elt, and oerat-ive to start a break in the web, whic break, due to the tensionunder which the web is being fed and the condition of the web at thispoint, will quickly continue laterally entirely across the web and causethe same 'to break clear through, suitable means bein providedcooperative with the traveling we at one or more points in advance ofthe blast means, and o crating in the'event' of the accidental partingof the web, to automatically bring the blast means into action. It willbe understood however that the invention in its broader as sets is notlimited to this particular embo. iment, but includes as well, otherforms and embodiments which will operate to bring about thedesiredresults.

The detailed form and construction of the mechanism and the cooperationof the parts thereof will be fully set forth in thespecification tofollow, and'the novel features thereof set out in! the appended claims.

Fi 8 is a fragmentary view in elevation showing the relation of theshower pipe to the forming wire to enable the latter to be freed ofadhering pulp.

Referring to the drawings:

Referring to Figs. 1 and 2 which show conjointly a Fourdrinier papermaking machine, 1 indicates the usual endless forming wire onto thereceiving end of which the pulp, from a supply tank or chest 2, isdelivered, the said wire in its travel, supplemented by the usualsuction boxes (not shown), forming the pulp into a moist selfholding web3 which passes from the deliver end of th( wire supported by the coucrroll 1, to the conveying felt 4 of the first press 5. The felt 4 carriesthe Web between the first press rolls 6, and the web issuing therefromis carried by the felt to the press felt 7 of the second press 8, andafter passing between the rolls 9 of the second press, it passes to thethird press 10,

and after issuing from between the rolls 10- of this press it passesonto the baby dryer cylinder 11, whence the web passes back and fortharound the main drying cylinders 12 and finally leaves the last dr ingcylinder of the series and passes into t 1e calender stack 13. 1

In accordance with my invention, means, in the present instance in theform of a fluid blast deliver nozzle 15, is employed to cause the breaof the traveling aper web when the web parts accidentally in its travelthrough the machine, which nozzle is arranged to direct the blastagainst the web at the point where the web is in a moist condition andcan be readily disintegrated by the action of the blast. The web is inthis condition at the point where it passes from the couch roll 1' tothe first press felt,

the blast nozzle bein arranged to point irect the blast, preferably air,against the portion of the web 3 bridging the s ace between the couchroll and the guide r0 1 7 of the first press felt.

The nozzle is supplied with air under ressure from a suits. e source ofsupply y a pipe 16 which is furnished with a manually operated cut-ofivalve 17, whereby the air blast may be shut off at will as will bepresently explained more in detail. Between the valve 17 and blastnozzle, the supply pipe is furnished with a valve 18 for the automaticcontrol of the blast in' accordance with my invention, which valve isnormally closed so as to shut off the blast in the normal travel of thepaper web through the machine. but which is adapted to be openedautomatically in the event of the accidental parting of the web, so asto permit the blast to then act on and cause the web to break andthereby prevent the further feed of the web through the machine at thispoint.

To effect this object, valve 18 is operated by electrical means in theform of a solenoid core 19 surrounded by asolenoid coil 20 included in anormally open power circuit 21 more fully described hereinafter, whichwhen closed will cause the coil to move the solenoid core endwise, and,through the medium of links 22 connected res ctively with'the core andvalve, turn the atter to open position and release the blast.

The closure of'the power circuit is efl'ected automatically when thepaper web parts accidentally, by means of contactors in a normally opencontactor circuit 23, which contactors are arranged at a number of ointsin the machine. contactors 2424 at di erent points in the three presses,a contactor 25 at the baby dryer, and contactors 26-26, etc., in themain dr or section. The contactor circuit when 0 osed, will through themedium of electrically operated means more fully described later on,close the power circuit 21 and will thereby turn on the air blast, andsuch closure of the contactorcir- 'cuit will take place in the event ofthe accidental parting of the paper web. To effect this closure of thecontactor circuit, the contactors 24 in the presses are of a form whichwill be held in open position by the tension of the web when the latteris traveling normally through the machine, but which, when the tensionof the web is relieved, as when the web parts, will automatically closeand will thereby close the contactor circuit. And the contactors 25 and26 cooperative with the drying cylinders, are of a form which will beheld open by the presence of the web on the cylinders in the normaltravel of the web, but which whenthe web parts and the leading end ofthe broken web passes from between the contactors and cylinders, willcontact with the cylinder and thereby ground through the machine andclose the contactor circuit.

The contactors 24 are each in the form of a lever 27 as best shown in Fi4 pivoted between its ends as at 28 to a h ired art of the machine framein such position t at one end of the lever will rest upon and besupported by the paper web where it passes from the delivery end of thefelt of one press to the receiving end-of the felt of the next press,the tension of the web in its normal travel through the machine thisholding the lever in a position which will hold opposite end out ofcontact with a contact plate 29. The leveris grounded through themachine frame as at 30 by a conductor 31 and the contact plate 29 isconnected in the contactor circuit 23, which latter is grounded throughthe machine as at 32 as will be presently described .more in detail. Asa result of this form and arrangement of the contactors 24, when thepaper web accidentally parts at a point in rear of any of the threecontactors', the tension of the web being relieved, will allow that endof thelever bearing on the paper, to descend and the opposite end willrise in contact with the contact plate 29, thus closing the contactorcircuit and turning on the blast, which impinging upon the paper web atthe point between the couch roll and first press felt will cause the webto break at this point.

tactors 24 will thus act to turn on the blast v The conwhenever theaccidental parting of the web occurs between the first and second pressor between the second/and third press, or between the third press andthe baby dryer,

The power circuit 21 before alluded toas o crating the solenoid core 19,may be supp ied by adirect or by an alternating electric current. In thepresent instance I employ an alternating'current from a power supplyline furnished with a transformer 39.. said power circuit normally isopen-at the spaced contact points 40 and 41, and starting at point 41, aconductor 42 leads to the solewith a conductor 45 which in turn connectswith a conductor 46 leading to the transformer 39", and a conductor 47connected with the transformer leads to the contact point 40. This powercircuit, as before explained, is normally open when the machine isoperating under normal conditions with the paper web passing throu 'hthe machine intact, but it is adapted to closed when the paper webaccidentally parts, as previously described, by an electrlcally operatedswitch mechanism 48 controlled in its opera tion by a relay 49, which inturn is operated by the contactor circuit 23;

The switch mechanism 48 comprises in the present instance an endwisemovable rod 50 car ing four switch arms 51, 52, 53' and 54 insu atedfrom said rod. The rod carries a solenoid core 55 surrounded by-asolenoid coil 56, which coil when energized will hold the rod'in theposition shown, with the contact switch arm'51 free of the contact oints40 and 41, with which said arm is a apted to contact to close the powercircuit when the coil is deenergized.

The switch arms 52 and 53 are adapted to contact respectively withspaced contact points 57 and 58, and with spaced contact points 59 and60, at different points in the contactor circuit; and the switch arm 54is The adapted to contact with contact points 61 'and 61" included-inaswitch operating cirtheir associated contact points and maintaining thecontactor circuit and switch circuit closed at these oints, when thecore is energized and is olding the power circuit open, but moving todisengage the contact points and opening the c1rc'uits"at these points,when the coil is deenergized to close the powercircuit. v

In the switchcircuit 62- at another point, these are two spaced contactpoints 63 and.

64, at which point the circuit is controlled by the relay 49, andstarting at the point 64 a conductor 65 leads to the conductor 45 whichjoins conductor 46 connecting with the transformer and returning fromthe transformer the current passes by conductor 47 to conductor 66,thence to conductor 67 connecting with contact pointw6l, whence thecurrent passes by switch arm 54 to contact point 61, thence by conductor68 to a normally closed hand-operated switch 69, and leaving the switchthe current passes by conductor T0 to the solenoid coil 56, which coilis connected with the contact point 63 by conductor 70.

The relay 49 normally maintains this switch circuit thus traced, closedat the spaced points 63 and 64, and it opens the circuit whenever therelay is operated by the closing of the contactor circuit. To effectthis object, the relay carries a switch arm 71 normally contacting withthe contactor points 63 and 64 in the switch circuit, and the relay isoperated by a solenoid core 72 surrounded by a solenoid coil 73 includedin the contactor circuit, the said coil when decnergized, as'in itsnormal condition, holding the switch arm in contact with the contactorpoints 63 and 64 and maintaining the switch circuit closed, but whendeenergized, causing the switch arm to disengage the contact points andthereby open the switch circuit.

This contactor circuit receives its current from the transformer, andthe current flows through the following conductors constituting thecircuit. Contactor bus conductor 74 has connected with it the branchconductors 31 and 38 leading from the several contactors associated withthe presses and the dryer cylinders, and said conductor 74 leads to thecontact point 59, from which the current passes through switch plate 53to contact point 60, thence by a conductor 75 to conductor 66, thencethrough conductor 47 to the transformer, and returning from thetransformer by conductor 46, the current passes through conductor 76connecting with the relay coil 73, and traversing the relay coil thecurrent passes by conductor 77 connected with contact point 58. Thecurrent then passes through switch arm 52 to contact point 57 connectedto conductor 78 of the contactor circuit which is grounded through themachine frame at 32, as before explained.

in the operation of the parts above described, when the contactorcircuit is closed by the closing action of any of the contactors, therelay switch arm 71 will open the switch circuit at the spaced contactpoints 63 and 64 by disengaging said contact points, and the solenoidcoil 56 which had been holding the core 55 up with the switch arms57 outof contact with the contact points 46 and 41 in the power circuit, beingdeenerglzed, will permit the switch rod 50, and conse- .quently theswitch arm 51, to move into contact with said contact points 40 and 41and thereby close the power circuit.

controlling valve 18v and permit the blast to act in effecting the brakeof the web. This same movement of the switch rod 50 in closingthe powercircuit, will, through the medium of the switch arms 52 and 53, open thecontactor circuit at the points therein where the spaced contact points57 and 58 and the spaced contact points 59 and 60 are located, and theswitch arm 54 will open the switch circuit at the point therein wherethe spaced contact points 61 and 61 are located. By the opening of thecontactor circuit in this manner, the relay coil 73 being deenergized,the relay switch arm 71 will move back to contact with contact points 63and 64 of the switch circuit and this circuit will be again instantlyclosed at this point. But it will remain open at the point therein wherethe contact points 61 and 61 are located, and in order to complete theclosure of the switch circuit so as to again open the power circuit andshut off the blast, whose momentary action only will be necessary tostart the break in the web, a normally open resetting switch 79 adaptedto be manually operated, is employed. This switch is located in a branchcircuit 80 of the switch circuit, which circuit 80 branches around thegap in the switch circuit opened by the switch arm 54 as described, andcomprises a conductor 81 connected with conductor 67 and connected alsowith one of the switch points 82 of the resetting switch, the otherswitch point 83 of the switch being connected with the conductor 68 ofthe switch circuit. lVhen this resetting switch is closed, the currentwill flow from the transformer by conductors 47, 66, 81, switch 7 9,normally closed manually operated switch, 69, conductor 70, coil 56,switch plate 71, conductor 65, conductor 45, and conductor 46 back tothe transformer. This will energize the switch coil 56, and the switchrod 50 will be shifted endwise and the switch arms51, 52, 53 and 54operated to open the power circuit, and close the contactor circuit, andthe switch circuit at the contact points 61 and 61".

It will be understood that before restoring the parts to their formernormal condition by the operation of the resetting switch as justdescribed, the paper web broken by the blast must be again startedthrough the machine so as to hold the contactors 24, 25 and 26 in aposition which will open the contactor circuit, otherwise and if theresetting switch were operated before the travel of the web wasreestablished, the contactor circuit being closed, due to the absence ofthe web with which the contactors cooperate, the rela would be operatedto again open the switch circuit.

The clos. ing of the power circuit will open the blast of: the machine,thereby avoiding any In the action of the blast in causin the break ofthe web between the couch rol and first press felt, the blast blows the,ruptured web downwardly and because the ,web at this point is weak andunpressed, it can be returned without trouble to the supply tankrepreparation of the wet broke to enable 'it to be again supplied to themachine.

chine, and assoon as it arrives at the calender-st-ack, the resettingswitch. 79 is,0p erated to restore the mechanism to its former normalcondition in readiness for the next the feed of'the paper-web.-

The only function of the relay 49 is to give a momentary impulsesufiicient only to break the switch circuit. Therefore the acc'u'mulation of dirt, or other foreign substances on the surface ofthedryer cylinders,

or on the associated contact-ors, will not interfere with the momentarrelay; and a'contact of t e contactor rods for a single instant with thecylinder, followed by interruption 'due to dirt, will be suflicient tobring the switch mechanism 48 into action, which latter will operatewith definite power and reliably, to close the power circuit. 'It' isseen therefore that it would not be desirable to operate the mast meansdirectly from the contactor circuit, since, due to the'liabilit ofinterruption of the circuit from the c ogging of the surfaces 'by dirt,the blast -'wo'uld operate inter- 'mittentlyand inefiiectively with arapid puffin action.

he relay coil 73 has a high resistance relatively to the switch coil 56and therefore takes a relatively small amount of our- 1 rent. Underthese circumstances therewill be but little, if any, sparking betweenthe contactors and parts of the machine with which-they engage, so thatthere will be little or no liability of pitting 'the cylinders or p'therparts 01 the machine with which the cohtactors cooperate,

a; It will be understood that but a momentary operation of the blastwill be necessary to start the break of the web at the point where itpasses from the couch roll to the first press felt. It is the practicetherefore of the'attendant, to turn'ofl' the blast by the cut-off valve17, just as soon as the break actuation of the is started, and then whenthe power circuit has been opened again by the resetting switch and thevalve 18 thus closed by the deenergizing of the coil 20, the attendantagain opens valve 17 so that the blast will be ready ,to' flow 0n thenext automatic operation of the'parts.

Or the nearly closed position so as toallow the air to bleed throu h,and accumulate pressure in the pipe tween the valve 17 and theelectrically operated valve .18. As thus set, when the valve 18 isturned on, the accumulated pressure in the pipe back of it will causethe air to issue from the nozzle in a sudden pufi or blast which will besuflic'ient to start the break in the web. Under these conditions thevalve 18 can be left open,

without material waste of air and until the attendant, after the new webhas been started through they machine, opens the power circuit by theresetting switch 79 and thereby causes the closure of the valve 18, itbeing understood that while this latter valve remains open, the airbleedin by the nearly closed valve 17 will'escape in but very smallquantity. On the closure of the valve 18, the air bleedingpast valve 17will again build up pressure in the pipe back of the valve-.18 ready foranother blast or puff through the nozzle when the valve 18 is againopened. I 1

In order to preventthe accumulation of pulp on the forming wire in thecontinued travel of the wire and the continued feed of the ulp theretoafter the web is broken by the last, which accumulation would result inthe fall of the pulp from the felt in the lower stretch of the wire atdifferent points and the littering up of the floor, and loss ofmaterial, I provide means, brought into ac- 1 tion automatically on theparting of the web, or when the breaking b ast is brought 1nto action,which means will act to shower the lower stretch of the wire and free itof. "the adheringpulp. This means is shown in Fig. 1, and in the presentinstance consists of a fixed shower pipe 84 extended horizontallytransversely above the lower stretch of the wire just behind the couchroll, and suitably su ported from the frame of the ma chine, t e saidpipe being formed in its underside with erforations1-84 throu h whichjets of a suita le cleansing fluid, sue for instance as white wa'ter,will issue and fall on the travelin wire. The pipe is connected with asuitable source of liquid su ply, and

' is provided with a normally close controlling valve 85 whosestem isoperatively connected with a solenoid core 86 surrounded by a COll 87connected by electric conductors 88 and 89'to the conductors 42 and 44of the power circuit 21. The form and arrangement of the parts are suchthat when the power circuit is open and the coil 87 deencut-off valve 17may be set to ergized, the valve will be in closed position shutting offthe shower, but when the circuit is closed as by the accidental partingof the web or when the switches 69 are operated to turn on theweb-breaking blast independently, the coil 87 will be energized and willopen the valve and thereby turn on the shower. The shower will act toflow through the wire and clear the same of adhering pulp, and thelatter will fall down and be collected in a suitable saveall tanl 9Oarranged beneath the Wire at the point where the shower acts, and fromthe tank the col,- lected material may, by suitable means, he conductedaway for use again in the machine In order that the workmen may beinstantly notified of the occurrence of the accidental parting of theweb, I propose to provide signaling means which will be rought intoaction automatically when the web parts. In the present instance thesesignaling means are in the form of electric lights 84 laced in the powercircuit as shown in li ig. 1; or electric bells or other forms of sialing means may be employed adapted to h: brought into actionautomatically when the power circuit is closed by the accidental partingof the web. Or a whistle or siren 91 may be applied to the air blastpipe beyond the valve 18 in order to give audible signal when the blastissues on the opening-of the valve.

The normally closed hand-operated switch 69 in the switch circuit 62 isfor the purpose ofopening said circuit and thereby operat ing the webbreaking blast independently of the automatic operation of the same bythe parting of the web. Such hand-operated switches may be located atdifferent points in the machine so as to be within convenient reach ofthe workmen at diflerent points of the machine, who by the operation ofthe switches, may, when occasion arises, stop the further feed of theweb by operating the blast means to break the web.

Among the many advantages flowing from the invention as above describedmay be mentioned the following:

By the immediate detection of the parting of the web and the instantcutting off cit" the feed into the presses, the period of suspendedproduction is greatly shortened. In the event of the artlng oi the webin the presses, the bro e which is discharged onto the broke troughs ofthe presses, is small and there is no dan er of the accumulated brokebreaking t e felts when it ispassed from one press felt to the nextpress. Also the press felts are saved from sudden strain.

In case of the parting of the web in the dryers the fed sheet cannotbuild up a large accumulation of broke which would require much time inthe removal by the WOlllZ- men who in effecting such removal employ longspears. Under ordinary conditions the removal of the broke by spearscauses accidents to workmen standing by and may injure the dryer canvasor other dr *er parts. The removal of the broke in this mannernecessitates in most cases the stoppage of operation of the whole dryersection, and the starting up of the section causes always severe strainon the gears and bearings. Therefore it is most desirable to keep thissection in motion.

Due to the immediate cessation of the feeding of the material when theweb accidentally parts, there is economy in the con sumption of thesteam, since the dryers do not have to supply heat energy tounproductive paper. It also saves energy, in curtailing the power whichwould otherwise have to be employed in heating and pumping the so-calledbroke, and saves power also on the idle running machine. There is asaving of labor throughout the machine and at the heaters, andobstructions on the machine floor and around the broke heaters isavoided. The dryer canvas is saved. from strain by avoiding the wrappingof the sheet around the cylinders by large lumps of broke passingbetween the cylinders, rolls and canvas. The worl men are relieved fromstrenuous watch an they are given more liberty for their other duties,and gear troubles are minimized by preventing the clogging of the sameor contact therewith of the paper.

It willbe manifest however that these objects may be variously changed andmodified without departing from the limits of the invention; and furtherit will be understood thatthe invention is not limited to any particularform or con struction of the parts except in so far as such limitationsare specified in the claims.
